citrate (SDC) antimicrobial, confirmed today that the U.S. Environmental
Protection Agency (EPA) published in today`s Federal Register (Vol. 74, No. 110)
a new regulation establishing a particular form of silver ion technology as an
active ingredient for the sanitizing of food contact surfaces. The petition was

surface sanitizer, but the publication of this rule is an important step for
expanding the uses of silver dihydrogen citrate.
